This picture taken on November 26, 2016 shows one-year-old male elephant “Gold” playing inside the Dak Lak Elephant Conservation Centre (ECC) where he is being cared for in the central Vietnamese highland province of Dak Lak. Elephants used to roam freely in the area, mingling with potential mates, but human settlements have cut off once-popular breeding circuits. Now there are fewer than 100 elephants left in the wild and just 80 or so in captivity, mostly used to ferry tourists around the leafy forests of Vietnam's central highlands.
